Winters 1-1/2 inch Dial Size, Economy Utility Dry Pressure Gauge, Bras

The Winters PEM series pressure gauge features brass wetted parts, a circular dial encased in steel, and a male connection. It measures pressure with a dual scale (psi/kPa)/(Hg. vacuum/kPa) with an accuracy of + or – 3/2/3%. The brass wetted parts are designed for measuring non-corrosive liquids and gases. The black-painted steel case is IP52 certified for protection against dust and liquids. The circular dial comes in 1.5″ (40 mm), 2″ (50 mm), 2.5″ (63 mm), and 4″ (100 mm) diameters with an aluminum black pointer. The lens material varies for different diameters – polycarbonate for 1.5″, 2″, and 2.5″ dials, and glass for the 4″ dial. This gauge meets ASME B40.100 Grade B accuracy standards with a male connection at the bottom or center back, available in 1/4″ NPT or 1/2″ NPT. The bourdon tube is phosphor bronze, movement is brass, and welding is silver alloy. The gauge has a 25% over-pressure limit and a working pressure up to 75% of full scale value. Operating temperature ranges from -40 to 150 degrees F (-40 to 65 degrees C), making it suitable for various applications including plumbing, heating, air conditioning, and more.

Pressure gauges are crucial instruments for measuring gas or liquid pressure in vessels, ensuring optimal pressure levels for different applications. They can measure pressure relative to a reference point, such as gauge pressure relative to ambient air. Differential pressure measures variations between two points, while absolute pressure gauges measure relative to a vacuum. Winters Instruments, established in 1953 in Toronto, Canada, specializes in manufacturing various instruments including pressure gauges, thermometers, diaphragm seals, and pressure transmitters.
